[0026] As a further implementation of this solution, the angle between the support block 416 and the scraper 415 is 90°, and a plurality of support blocks 416 are provided. The support blocks 416 are distributed in a circular array at the bottom of the scraper 415, and one side of the support block 416 is arranged in an arc shape. Such a design strengthens the mutual support between the components and improves the structural strength of the device.

[0027] As a further implementation of this solution, the bottom end surface of the buffer net 417 and the bottom end surface of the scraper 415 are on the same horizontal plane, the buffer net 417 and the hollow tube 413 are on the same axis, and the central axis of the buffer net 417 and the central axis of the rubber bucket 429 are on the same straight line.

[0028] As a further implementation of the present invention, the angle between the rotating rod 424 and the rotating frame 423 is 90°, a plurality of connecting pins 425 are provided, and the connecting pins 425 are distributed in a ring array, and the angle between the connecting pins 425 and the sliding short tube 426 is 90°, and the upper end of the buffer spring 427 is fixedly connected to the connecting pin 425.

[0032] Working process: when the device is in use, the splash-proof bucket 41 is installed at the lower end of the discharge hopper 3. At this time, the raw materials are poured into the feed hopper 2, and poured out from the discharge hopper 3 after being stirred by the tank body 1. The concrete poured out of the discharge hopper 3 enters the hollow tube 413 through the connecting pipe 411. The buffer net 417 will intercept the concrete falling from the hollow tube 413 to prevent large agglomerates from falling directly and causing damage to the rubber bucket 429. When the material discharge speed needs to be accelerated, the rotating rod 424 is rotated to drive the fixedly connected rotating frame 423 to rotate. When the rotating frame 423 rotates, it will drive the fixedly connected grooved ring 421 to rotate. After the grooved ring 421 rotates, the relative position with the hollow tube 413 changes. When the grooved ring 421 moves, it drives the connecting pin 425 to move through the rotating frame 423. The connecting pin 42 The movement of the sliding short tube 426 drives the movement of the buffer spring 427, and the movement of the sliding short tube 426 drives the clamping claw 428 and the rubber bucket 429 to move. At this time, the relative position of the scraper 415 and the rubber bucket 429 also changes. The scraper 415 will scrape off the concrete attached to the inner wall of the rubber bucket 429. At the same time, the support block 416 will expand the rubber bucket 429 to make the bottom opening of the rubber bucket 429 larger, thereby improving the material discharge efficiency. When the concrete falls, the friction force generated between the rubber bucket 429 and the rubber bucket 429 will cause the rubber bucket 429 to move downward. The downward movement of the rubber bucket 429 drives the clamping claw 428 to move downward. The downward movement of the clamping claw 428 drives the sliding short tube 426 to slide on the outer side of the connecting pin 425. The sliding short tube 426 will generate a pulling force on the buffer spring 427, causing the buffer spring 427 to deform, thereby achieving a buffering effect.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
